重构: 拆Dashboard.vue仪表盘(strategy前端·Dashboard<500达标)

- 新建 components/dashboard/(StatCardRow 126 + ActiveProjectsPanel 174 + IdeasPanel 82): 统计卡+活跃项目+灵感池
- Dashboard.vue 563→238(<500达标): 头部+refresh+loadAll编排+共享样式
- store共享(useProjectStore单例, 子组件纯读, 无props/emit)
strategy: 前端views, 子组件三拆; Dashboard<500达标(第四个继Ideas/Knowledge); scoped .df-panel父子各存(隔离必需)
